i Application filed May 23, 1925. Serial No. 32,368.

i relates particularly to fiashings for gravel roofings, shingleroofings, and the like and the object of the invention is to provide asimple inexpensive device. which will be easily attached to a buildingto prevent water, snow and the like from passing through the jointsbetween the roof and any upwardly projecting portions such'as, surroundiwall, chimneys, ventilators, sky lights or such like structures.

Another object is to provide a device of the class stated which will beattached to the building without the use of nails, cleats, rivets orsuch like holding means, which penetrate the flashings and reduce thelife of same.

A further object is to provide a device of the class stated which willbe neat in appearance, and economical as far as erection and maintenanceis concerned. 1 o

In my invention I provide a holding member for the flashing, saidholding member being held in position in the wall by pro-.

viding a plurality of perforations in it,

through which the cementing material, used between the bricks formingthe wall, passes to form an anchorage-for the member. -A portion of theholder is bent over to form a guide for the upper edge of the flashingwhich is slidably mounted therein, and .is provided with a part adaptedto lie parallel with the face of the wall. The lower edge of theflashing is bent to carry water or the like on to the roof or to thegutters as desired. Part of the holding member in the initial sta e oferection rojects outwardly from the ace of the wall in the horizontaldirection, and is used as a holding means for the flashing b being bentover the uppermost corner 0 the flashing thereby forming what is knownin this art as a counterflashing 7 I v the drawings Figure 1, is aperspective view of my preferred type of flashing used for gravelroofmg.

Figure 2, is a sectional elevation taken on the line 2-2 Figure 1. y

- Referring more particularly to the drawing, 11 designates a brick wallof the usual construction which projects upwardly from the edge of theroof designated as a whole by the numeral 12, and built in any of thestandard well known methods. Between the bricks are the usual mortar orcement joints 13. Placed between the bricks and held in place by themortar joints is a flashing holder formed from a single sheet of metalbent to provide a U-shaped guide 14 having relatively long upper andlower legs 15 and 16. The lower leg 16 is doubled upon itself to providea rear extension 17 projecting beyond the curve of the guide 14. Thisextension is formed with a ridge 18 and with openings 19 so that whenthe holder is placed between two bricks as shown in Figure 2 the mortaror other cement employed between the bricks will be disposed at oppositesides oftheridge-and throughsaid openings so as to securely anchor'theholder in place. The two thicknesses of material at the forward end ofthe leg 16 are bent downwardly as at 20 to lie'flatly against the faceof the wall.

The flashing 21 is disposedto lie parallel with the face of the wall andis provided at its upper edge with a flange 22 fitting be-' tween thehorizontal portions of the legs 15 and 16, the upper port-ion of theflashing The forward terminal 15 of the leg 15 normally projects he ondthe face of the wall as indicated by 11 lines in Figure 2 but when theflange 22 is in place this terminal is bent downwardly against the bodypore tion of the flashing as indicated by dotted lines. At its loweredge flashing '21 is bent outwardly and downwardly as indicated at 23 sothat water accumulating thereon will be directed toward the center ofthe roof.

It will be seen'from the foregoing that I have provided a very simpleand easily attached means for holding the flashing which maybe placed inthe guide, and held therein by simply bending the uppermost edge of theholding member over the corner of the flashing to hold same in position.It is very neat in appearance and is easily'erected in position.

Modifications may be made in thedevice I om the spirit of the injectbeyond the face of the wall in which the holder is embedded, said lowerleg being folde'd upon itself to provide a double thickness of material,said folded portion being extended beyond tlie curve of the U in.parallel relation thereto and being formed with a ridge located closeto said curve, the two thicknesses of material forming the lower leg' 1being bent to'extend downwardly from a leg and provided at its upper awith lflange fitted in the space reserve between the two legs, theportion of the up r leg which normally projects outwardly hiyond II thedownwardly bent portion of the lower leg" being bent downwardly to clampthe I flashing against the correspondingly bent portion-of the lowerleg.

In witness whereof, I hayehereunto set 20 my hand.
